System with valve device for a pneumatically operated brake system, valve device, brake actuation device, trailer control valve device, and device for controlling for the system, brake system, vehicle, use of a component, and method for retrofitting

Abstract

The invention relates to a system (1) having at least one valve device (4, 4', 4'', 4''') for a pneumatically operated brake system (90, 90') of a vehicle, wherein the brake system (90, 90') has the valve device (4, 4', 4'', 4''') and at least one brake (92, 94, 98, 100). By means of the valve device (4, 4', 4'', 4''') a pneumatic brake pressure which can be fed to the brake is adjusted in a controlled manner. According to the invention, the system has at least two variants (12, 14) of the valve device (4, 4', 4'', 4''') which can be used alternatively in the brake system (90, 90'). Here, a first variant (12) is configured as a modulator for use in an electronically regulated embodiment of the brake system (90), and a second variant (14) is configured for use in a pneumatically controlled embodiment of the brake system (90'). However, both variants (12, 14) of the valve device (4, 4', 4'', 4''') have pneumatic interfaces (24, 26, 28, 30) and mechanical fastening points (16, 18, 20, 22) which are configured identically with respect to one another. Furthermore, the invention relates to the valve device (4, 4', 4'', 4''') for the system (1), and a brake actuation device (6, 6', 6'''), a trailer control valve device (8, 8') and a device for controlling (10, 10') in each case for this system (1). Moreover, the invention relates to a brake system (90, 90') for a vehicle with at least one replacement component (2) of the system (1), to the vehicle, the use of a component of a brake system as component (2) of the system (1), and a method for retrofitting a brake system, in which method a component of the brake system is replaced by a component (2) of the system (1) according to the invention.

Description

technical field [0001] The invention relates to a system with at least one valve arrangement for a pneumatic brake system, eg of a motor vehicle. Such a brake system has a valve arrangement with at least one valve for modulating or boosting the brake pressure and at least one brake, ie usually a brake on each wheel of the vehicle. In response to an actuation of the brake actuating device, for example by means of the foot brake pedal, the pneumatic brake pressure is modulated by means of the valve device and supplied to the brake via a compressed air line or tube. [0002] Furthermore, the invention relates to components of the system, in particular to a brake actuating device, a valve device, a trailer control valve device and an electronic control unit, a brake system, a vehicle and a method for retrofitting a brake system with these components. Background technique [0003] Braking systems are known in various embodiments, namely in one embodiment as a purely pneumatic br...

Problems solved by technology

This makes both initial equipment and retrofitting of the vehicle costly

It is particularly complex to convert a vehicle with EBS brake system into a vehicle with ABS brake system (without EBS) or a purely pneumatic brake system (without ABS)
